    Introduction: Mobile phone technologies have been promoted to improve adherence to antiretroviral therapy (ART).We studied the receptiveness of patients in a rural Ugandan setting to the use of short messaging service (SMS) communication for such purposes. Methods: We performed a cross-sectional analysis measuring mobile phone ownership and literacy amongst patients of The AIDS Support Organisation (TASO) in Jinja, Uganda. We performed bivariate and multivariate logistic regression analyses to examine associations between explanatory variables and a composite outcome of being literate and having a mobile phone. Results: From June 2012 to August 2013, we enrolled 895 participants, of whom 684 (76%) were female. The median age was 44 years. A total of 576 (63%) were both literate and mobile phone users. Of these, 91% (527/ 576) responded favourably to the potential use of SMS for health communication, while only 38.9% (124/319) of others were favourable to the idea (pB0.001). A lower proportion of literate mobile phone users reported optimal adherence to ART (86.4% vs. 90.6%; p=0.007). Male participants (AOR=2.81; 95% CI 1.83=4.30), sub-optimal adherence (AOR=1.76; 95%CI 1.12=2.77), thosewithwaged or salaried employment (AOR=2.35; 95% CI 1.23=4.49), crafts/trade work (AOR=2.38; 95% CI 1.11=5.12), or involved in petty trade (AOR=1.85; 95% CI 1.09=3.13) (in comparison to those with no income) were more likely to report mobile phone ownership and literacy. Conclusions: In a rural Ugandan setting, we found that over 60% of patients could potentially benefit from a mobile phone-based ART adherence support. However, support for such an intervention was lower for other patients.

    Lack of Effectiveness of Antiretroviral Therapy in Preventing HIV Infection in Serodiscordant Couples in Uganda: An Observational Study.
    (2015-07-14) Birungi, Josephine; Min, Jeong Eun; Muldoon, Katherine A.; Kaleebu, Pontiano; King, Rachel; Khanakwa, Sarah; Nyonyintono, Maureen; Chen, YaLin; Mills, Edward J.; Lyagoba, Fred; Ragonnet-Cronin, Manon; Wangisi, Jonathan; Lourenco, Lillian; Moore, David M.
    Background We examined the real-world effectiveness of ART as an HIV prevention tool among HIV serodiscordant couples in a programmatic setting in a low-income country. Methods We enrolled individuals from HIV serodiscordant couples aged >18 years of age in Jinja, Uganda from June 2009 – June 2011. In one group of couples the HIV positive partner was receiving ART as they met clinical eligibility criteria (a CD4 cell count >250 cells/ μL or WHO Stage III/IV disease). In the second group the infected partner was not yet ARTeligible. We measured HIV incidence by testing the uninfected partner every three months. We conducted genetic linkage studies to determine the source of new infections in seroconverting participants. Results A total of 586 couples were enrolled of which 249 (42%) of the HIV positive participants were receiving ART at enrollment, and an additional 99 (17%) initiated ART during the study. The median duration of follow-up was 1.5 years. We found 9 new infections among partners of participants who had been receiving ART for at least three months and 8 new infections in partners of participants who had not received ART or received it for less than three months, for incidence rates of 2.09 per 100 person-years (PYRs) and 2.30 per 100 PYRs, respectively. The incidence rate ratio for ART-use was 0.91 (95% confidence interval 0.31-2.70; p=0.999). The hazard ratio for HIV seroconversion associated with ART-use by the positive partner was 1.07 (95% CI 0.41-2.80). A total of 5/7 (71%) of the transmissions on ART and 6/7 (86%) of those not on ART were genetically linked. Conclusion Overall HIV incidence was low in comparison to previous studies of serodiscordant couples. However, ART-use was not associated with a reduced risk of HIV transmission in this study.
